The ARMagLock turns your firearm into a “fixed magazine” firearm that can not release the magazine unless you pull the takedown pin, and separate the upper and lower receivers, thus “disassembling” the firearm action.

Once the receivers are minimally separated, the ARMagLock can be engaged to release the magazine.

After many requests we have produced this illustrated photo guide to installing your own ARMagLock accessory on your own firearm.

You will need the following tools:

Pick Tool

Screw Driver (small)

Bullet Button Tool (optional)

Allen Wrench that is included

Needle Nose Pliers

May need Dremel or file for troubleshooting

Installing the Magazine Catch Bar:

First we will show you how to remove your magazine release button. If you are outside of California, simply press the magazine release button as far as it will go and twist the magazine release catch counter clockwise until it is fully out.For those of you in California that have a Bullet Button, either use a screwdriver if you have a Raddlock, or a bullet button tool to loosen the magazine release button. If you have a factory installed bullet button that is glued in, heat up the bullet button to soften the glue before unscrewing.In this case we will use a screw driver to remove the magazine release button.Take your ARMagLock and place the spring on the standoff (cylindrical threaded tube). Next put into the magazine release button well.Depress the ARMagLock completely into the magazine release button well.On the left side of the firearm, tighten the cap screw on firmly, but do not tighten all the way. Line up the ARMagLock so that the top lip is flush with the upper receiver. While holding it in place, with you Allen wrench tighten the cap screw until snug.Tighten with an Allen Wrench

Notes for troubleshooting:

1. After installation of the ARMagLock the button is loose in the lower, to the degree that the magazine can be removed without separating the upper and lower receiver and pushing the button.

a. It should be tight enough that the magazine catch bar keeps magazines from being pulled out even with force, just like an OEM magazine catch. Tighten the cap screw until the desired fit is acquired.

2. After installation of the ARMagLock the button is tight in the lower, to the degree that the lip is jamming between the upper and lower receivers when attempting to close them.

a. It should be tightened to the point that the magazine catch bar holds magazine in place but not so tight it jams the upper bar between the upper and lower. If the required tightness for magazine retention continues to place the upper bar between the upper and lower receives when attempting to close, remove a few thousands of an inch (with a Dremel, light file or sand paper) off of the upper edge. (see image below) Continue until the upper lip is flush with the upper receiver when closed.

Remove a few thousands of an inch off of the upper edge.

Replacement of Rear Takedown Pin:

The easiest way to remove your takedown pin without undoing the castle nut and stripping the staking is to do the following. Pull the rear takedown pin and open the receiver.

Push the takedown pin back in slightly to disengage it from the detent pin.Use your pick tool to push the detent pin back into the lower receiver to clear it for removing the takedown pin.With the detent pin held back, fully remove the takedown pin. The detent pin will stay seated in the detent channel.Use your pliers to pull the detent pin back until you can hold it in place using your flathead screwdriver.Now take your flathead screwdriver and insert it through the left side takedown pin hole. Push the detent pin back into the detent channel in the lower receiver with your screwdriver. Ensure you keep the head of the screwdriver perpendicular to the floor.Quickly insert your custom made ARMagLock takedown pin while holding the pin back.Perform a function test to ensure your ARMagLock is working properly.

It’s really getting ridiculous that people have to come up with such crap to exercise their God given right to self defense. I will never live in any of the Constitution Free Zones that have been established by liberal/progressives.

I can understand your frustration, but I think you guys are coming at this from entirely the wrong angle.

Having lived in California, I can tell you that It many decent and down-to-earth gun owners, and gun owners from whom I learned a great deal about firearms, be it safety, laws, or politics. They are not a political majority, but California is a big state, and even a minority in a state of 38 million represents a whole bunch of allies whom the CA legislature would love to Bataan-death-march into the Pacific if they thought they could.

The advent of the bullet button and similar such devices was a stunning coup for gun owners behind enemy lines. If not for the intellect and creativity of CA gun owners, that state’s ban on ARs and AKs would still be alive and well today.

It was a victory that allowed me to legally purchase and own several AR15s and AR10s while I lived there. …and it was not just creativity, but hundreds of brave souls who served as the “test cases”, bringing these contraptions into mainstream acceptance over a period of several years. It has meant an influx of millions of these weapons over the past 8 years into the state, making future bans or expansions of bans ever more difficult.

Do not ever forget that our enemies are playing a long game. They mean to shrink their opposition (ie, us) by means of attrition. They mean to make it too difficult and legally dangerous for us to go shooting, to own certain types of firearms, and most importantly, to introduce new shooters (including our own children) to guns and gun culture. They mean to bring their war to to the next generation if they can’t win it against us directly.

Unfamiliarity makes for bogeymen, and our enemies’ strategy above all is to turn us and our guns into bogeymen by removing them from common experience. Every time we drive them back like this is a victory that can not be overstated. It means another 5-10 years of being able to take people out to actually shoot a REAL HONEST-TO-GOD AR-15 just like they see on the nooz!

It means those wide-eyed waifs get to see and touch and fire it and its ammunition side-by-side with a real hunting rifle, and to process their dismay at how small and low-powered this “high-powered death machine” really is. It means we can continue dragging these concocted bogeymen out into the light where they quickly burn away.

In fact, the frustration new shooters experienced with these magazine locks was better than any propaganda I could possibly have come up with on my own. I didn’t have to drone on with some long-winded gun-nut rant about how Kafkaeque CA’s gun laws were. I didn’t have to tell them how the burdens of these laws fall primarily upon those who obey the laws. I didn’t have to explain how these laws do nothing to reduce frequency or severity of violent crime in the real world.

All I had to do was let them fumble with that damned mag lock a few times, and remind them with a conspiratorial smile how much safer we all were for it. All I had to do was let them reflect on the hilarious proposition of a violent criminal installing one of these on his AR. The experience told them more about the imbecility of CA’s gun laws than they could ever have learned by hearing about it from me or anyone else.

Those kinds of experiences are what our enemies are trying desperately to stomp out. …and inventions like these ENRAGE them like nothing you’ve ever seen.

Do not EVER forget: California has a nasty habit of being the petri dish for breeding new laws that end up spreading across the country. We write off this state as a hopeless basket case at our own immense peril.

I urge you all to support the gun owners who live there, and support their fight. Instead of giving in to frustration and disgust, how about congratulating these people for their creativity at defeating yet another round of legislation meant to regulate them and eventually all of us out of existence? They truly are fighting behind enemy lines. …and as those living in CT, MD, CO, NY, WA, and OR have recently learned, the rest of us are not at all immune to the evil that besieges our brothers and sisters in the Golden State. Better to fight our enemies in Sacramento than in our own state capitols.

I can see these not passing muster in California if the new laws pass. The law, as written states that the mag lock can not be operated by a tool. With the cap head screw open to the outside, and accessible for loosening with a tool, I’m sure that these will quickly be lumped in with the bullet buttons and prosecuted as such. I suppose you could increase your odds by filling the socket head with epoxy so you can’t insert a tool into it.

It may, it may not. I ordered one today regardless. Living in California, I would rather have one on order then sit on the fence wondering. I almost purchased it a while ago. I like to support those fighting for our rights.

The mag lock isn’t operated by a tool; it installed with a tool. Any use of a tool on it after it is installed would only uninstall it and make the rifle unable to have a magazine in it at all. It’s all dependent on who is looking at it. I guarantee no LEO is going to see you use it properly and say “hey, you can use a tool on it… that’s not legal”. I see enforcement of this “assault weapons” ban being meager at best.

got this kit, install simple nuff, though installing magazine is not as advertised, but I can live with that vs not having my fire system to plink at targets. Busting open the rifle in half, and changing magazines is what the law wants, and they shall have. This kit is awesome to fit the way the bill was written. (though manufacturer will not say that this will satisfy the lawmakers) – but that is just lawyer talk to cover for any lawsuits, litigations. I see non, because of the design and how the law is written.

I still do not understand why lawmakers can justify passing a new law NOT TO FIX A PROBLEM, but the CREATE NEW CRIMINALS!!!!!! Ladies and gentlemen, if I was their boss, I would fire them for wasting taxpayers money on laws that don’t make sense.

Also, why do they want to collect more revenue for registration, when we already paid DROS fees when these rifles were originally purchased? Do people understand that once you register a fire system as an “ASSAULT WEAPON” it can’t be sold, or passed to next of kin upon death? Why are these rifles all of a sudden be labeled as an assault weapon? Ask any military if they want to go head to head in battle with a rifle that has a bullet button…. I wonder how many will define that rifle as a true assault weapon. Let me make a wild guess…. NONE! Therefore these lawmakers have no clue what an assault weapon system is, and should stick to things they understand, and don’t try to re-define an item to something it is not.
